As it had been determined to abandon completely the religious conservatism of the former reign it was felt absolutely necessary to remove the Catholic-minded bishops, to make way for men of the new school on whom the government could rely with confidence. Gardiner of Winchester and Bonner of London were already in prison. Heath of Worcester, who had refused to agree to the new Ordinal, was arrested in March 1550, as was also Day of Chichester in October. Tunstall of Durham, whose conservative views were well known to all, was placed under surveillance in May 1551, and thrown into prison together with his dean in the following November. In a short time a sentence of deprivation was issued against Bonner, Heath, Day and Gardiner. Bishop Thirlby of Westminster, who had given great offence by his uncompromising attitude regarding the Blessed Eucharist, was removed from Westminster, where his presence was highly inconvenient, to Norwich, and the aged Bishop Voysey was forced to resign the See of Exeter to make way for a more reliable and more active man. At the same time steps were taken in the universities to drive out the men whose influence might be used against the government's plans. The Sees of Westminster and London were combined and handed over to Ridley of Rochester, one of Cranmer's ablest and most advanced lieutenants. Hooper, who looked to Zwingli as his religious guide, was appointed to Gloucester; but as he objected to the episcopal oath, and episcopal vestments, and as he insisted on his rights of private judgment so far as to write publicly against those things that had been sanctioned by the supreme head of the Church, it was necessary to imprison him[63] before he could be reduced to a proper frame of mind for the imposition of Cranmer's hands (March 1551). Ponet was appointed to Rochester, and on the deprivation of Gardiner, to Winchester, where his scandalous and public connexion with the wife of a Nottingham burgher[64] was not calculated to influence the longing of his flock for the new teaching. Scory was appointed to Rochester and afterwards to Chichester, and Miles Coverdale to Oxford.
